Top Features of the Campagnolo Shamal Ultra Mega G3 Clincher 2-Way Fit Wheelset

Supplied with wheel bags

Two colour options available: Black, Dark Label

Wheel features

2-way fit technology allows you to either use the standard clincher or tubeless tyre

Differentiated rim heights which means 26mm at the front which provides optimal handling and 30mm at the rear for transmitting more power to the road

MoMag allows the external profile of the rim to be free of holes thus increasing structural resistance. Also makes rim tape unnecessary and reduces the weight of the wheel

Dynamic balance gives maximum stability of the wheel even at high speeds

Oversized flange for increased torsional stiffness

Carbon fibre hub body provides a high degree of lateral stiffness and reduces weight to a minimum

This has been achieved by a new production process that reduces the thickness of the rims but not the well-known strength of Campagnolo wheels. As for smooth riding, Shamal Ultra wheels are fitted with USB ceramic bearings that improve smoothness, extend the wheels' life time and further reduce their weight.

These new high end wheelsets represent a big step ahead in terms of performance and reactivity. To optimise the key features of a road bike wheelset, such as weight, aerodynamic and stiffness, engineers at Campy Tech Lab are always working hard implementing new technologies.

One of the new results of these efforts is the Mega G3™ Geometry, the further development of the G3™ Geometry, which optimises the spoke tension and delivers a long lasting performance. Furthermore, Shamal™Ultra™ wheelsets mount a new oversize drive side flange on the rear wheel that is now bigger and allows to increase dramatically the responsiveness of the wheels and the overall performance of the bicycle.

G3 TechnologyCampagnolo has developed an assembly architecture which, compared with a traditional wheel, makes it possible to improve energy transfer, reduce the stress on the spokes on the right and increase transverse rigidity. This is achieved because in G3 geometry the right-hand side of the rear wheel is fitted with twice as many spokes as the left.

The results of G3 system are truly extraordinary: better transfer of the driving torque, better lateral rigidity, reduction of the stress in the rear wheel spokes. And thanks to the G3 system that compensates for the forces acting on the 2 sides of the wheel, there are no more wheel vibrations, even for heavier people.

G3 becomes Mega-G3 thanks to the oversize flange. This solution allows the increase of the torsional stiffness values even more, to the benefit of the overall responsiveness of the wheel.

Mega G3 Spoke PatternPerfect balance of the spoke tensions on both sides of the wheel. Reduces stress, increases transversal rigidity and the transmission of power to the wheel. G3 eliminates vibrations even with "heavy" cyclists.

Dynamic BalanceThe concept is simple and elegant: balance the weight of the gasket, with an item of similar weight placed on the exact opposite side. For top models, this is obtained by a special operation on the section of the rim opposite the rim joint. For entry-level models, Dynamic Balance is obtained by using two oversized spokes in the section opposite the joint. The result is a wheel with perfectly balanced rotational dynamics.

MoMagA technology that offers several advantages to the structural integrity of the wheel as well as eliminating the need for rim tape. The name derives from “Mounting Magnet” system, shortened to MoMag.

2-Way FitWith 2-Way Fit™, you will be able to personally test which of the two solutions suits you best, clincher for training and/or tubeless tyre for the day of the race.

With no doubt tubeless tyres are the future of road cycling. Apart from greater comfort, the advantages are many: using a tubeless tyre you can exploit the greater smoothness due to the absence of friction between the tyre and the tube. There are no risks of sudden deflation when a tubeless tyre is punctured, a great advantage in safety terms. The lack of tubes eliminates puncture risks.

And what if the tubeless tyre has a puncture? The Campagnolo 2-Way Fit system allows you to use a traditional inner tube by simply removing the hermetic closure valve to ride home with no problem.

Excellent qualities
Thoroughly pleased with wheels. Light but being Campagnolo the quality is very good. Roll very well . Using 25mm schwable one appear to be a good combination.

Ultra light and ultra smooth
First upgrade for a carbon framed bike. Debated whether to go for carbon wheels then saw the Capagnolo Shamal Ultra 2 way fit wheelset at a great discounted price. I fitted these with 23C Schwalbe One tubeless tyres - sealed with Stan's No Tubes Sealant.
These wheels have been an excellent investment - they are light and seem to spin forever on the ceramic bearings. The ride on the 23C tyres is a bit hard but I haven't had any punctures in the first 500 miles.

Gorgeous wheels - tubeless a pig to fit
These are replacements for my 6 year old Shamals. Now 11 speed with ceramic hubs. They sprint and climb superbly. Comfy too with Hutchinson Fusions. Get some Stans no tubes rim tape and loosen the valve as you fit the tyre. I used tyre levers as Campag rims are on the large side. A pain to fit.

These wheels should be suitable for use although we'd recommend keeping an eye on the spoke tension and having them regularly checked and trued by a mechanic to ensure the rims do run the risk of warping due to loose spokes.

It might also be worth looking at something like Pro-Lite's Gavia wheels, as Pro-Lite rate their wheels as being able to accept a rider weight in excess of 110kg.

Answers

Answer:

you could but I wouldn't. Just because they have recommended doesn't mean you should use 28c. I've never heard of that before. You can run any size of tyre from 20c to 28c. I would recommend 23 or 25c though to get the best out of these wheels.

Answer:

Thanks Alex. I'm still not clear - "will be compatible" - does that mean that this is "in the future"?

I did some more research. The freehub body required for Shimano 11 speed is different from the 10 speed one - so it's not an automatic fit, and in 2012 they did not have the 11 speed part manufactured. They introduced it in 2013, and the part number of the 11 speed freehub is FH-BUU015X1 - please can you confirm that it will be supplied with this freehub body?

Fulcrum also manufacture a Shimano 11 speed freehub body - do you know if this is compatible?
